This time trying to make war against Soviet Russia with Germany, Azerbayan, Georgia, Armenia, Ukraine, Lithuanian, Latvia, Estonia, Finland and Polish Legions.

I want to declare war and crush the Western Whites, with wich I dont have an alliance, how to do so?

I have also recruited Prince Lieven, is he the key to declare war against Whites after you ally with them? Any interesting information about Lieven?

German troops are also trying to get further in Kazan, Samara and more regions, but they lack of food every 3-5 turns, and even Moskau und Petrograd aren't enough to supply them with food. Any idea?

I've noticed that the railway buy option was avalible in June and January every year in the same scenario, but in a separate game(I hope you understand what I mean here) even when it was 1928 and the scenario was already over. But in this new game, the railway buy option is barely avalible, haven't seen it for over a year and it's 1923, one year left for the game to finish. Help on how this works?
